A stone of \(1\ kg\) is thrown with a velocity of \(20\ m\ s^{-1}\) across the frozen surface of a lake and comes to rest after travelling a distance of \(50\ m\\). What is the force of friction between the stone and the ice?
 
From the Equation of motion, We know that,
 
iiii=i×i×i
 
From the Newton's second law, We know that,
  
Acceleration \(=\)     \(m\ s^{-2}\) 
  
Force acting on the stone\(=\)  \(N\)
